T 0 all whom. it may concern:

Be it known that I, JAMES P. MosIER, a citizen of fthe United States, and a. resident of the city of St. Francois, in St. Francois and State of Missouri, have invented a new and useful Improvement in Combined Material Removing and Conveying Machines, of which the following is a specification.

This invention relates to machines for removing and conveying materials, such as ore, coal and the like, wherein the. material is removed from the pile by means of a scoop and is then transferred to an endless rotary conveyer which delivers the material to the point of discharge. One of the principal objects of thelpresent invention is to utilize the scoop support, usually a boom, as a chute for delivering the material from the scoop to the endless conveyer. Another object is to utilize the forward. movement of the machine for forcing the scoop into the material and thereby dispensewith the mechanism -commonly used forY movably supporting the scoop and forcing the same into the material. Another object is 'to utilize the mechanism which lifts the boom and scoop as a means for dumping the scoop and swinging the yboom laterally. Another ,object is to produce a small and compact self propelled machine of light weight and of simple construction which can be readily moved about a-mine and can be operated by a single attendant.l

The inventionconsists principally in an arrangement of parts whereby the boom that carries the scoop serves also as a chute for the material delivered thereto from said scoop; it also consists in an arrangement whereby the boom that carries they scoop serves also to deliver the material from the scoop to the conveyer; it also consists in mounting the scoop on the end of the boom and adapting it to dump its contents onto said boom.; it also consists in a single means for rotating the scoop and swinging the boom sidewise and vertically; and it also consists in the parts and combinations and arrangements of parts hereinafter described and claimed. y

In the accompanying drawings, which form part of this specification, and wherein like symbols refer to like parts wherever they occur,

the county of means of hinge straps 11.

Fig. 9 is an enlargedaxial section through the mechanism for raising and swinging the boom; and

Fig. 10 is a perspective View showing the brake mechanism used in connection with the mechanism for propelling the machine.

The machine'` shown in the accompanying drawings comprises a rigid body portion 1 supported on axles 2 to which are xed anged car wheels 8 supported on rails 4; Heavy springs 5 are interposed between the .body 1 and the aXles'2 as in the ordinary locomotive truck. Attached to the rear of the wheeled body 1, by means of a coupling member 6, is an ordinary mine car 7.

Mounted on a casting 8 at the front end of the body 1 is a boom 9. The cross-sectional shape of the boom is of H-shape and has a hinge-piulO disposed crosswise .of its inner end and supportedr therefrom by These hingestraps 11 are riveted to the -underside of the web portion of the boom adjacent to the side margins thereof and have eye portions adapted to receive the ends of the hingepin 10. The portion of the hinge-pin 10 between the spaced straps l1 is journaled in the eye portion of a hinge-strap 12. The hinge-strap 12 rests on the upper surface of a plate 13, whose inner end portion rests on the upper surface of the end casting 8. The plate 13 extends forward of the end casting 8 and its outer en'd is suitably supported by 4means of a brace member l-l. A

pivot-pin 15 extends through alined open-v ings in the hinge-strap 12, the plate `13 and the upper flange of the end casting8, and is held in position by means of cotter pins. In consequence of the above arrangement,

the boom is permitted to swing' vertically end'with digger teeth 19; `and thel back of said scoop, in the normal or lowermost in thev opposite direction.

position thereof, bears against the outer end of a stopbar 20, whichprojects from the under side of the boom, whereby saidscoop is supported from said boom with its digger teeth clear of the ground.

Thescoop is swung about the pivot bolts 18 and the boom is swung both vertically and horizontally by means of chains 21 and 22. The. chain 2-1 is secured to the upper corner of one side of the scoop and is used for swinging the boom in one direction;

and the chain 22 is secured to the other upper corner of the opposite side of the scoop and is used for swinging the boom Eachr of these chains passes between a pair of horizontally journaled guide rollers 23 mounted on an upright frame 24 at the front end of the body 1. The chains 21 and 22 also run over horizontally journaled guide rollers 25 which are also supported on the upright frame 24, and thence onto winding drums 26 and 27 of the so-called planetary type. The drums 26 and 27 are loosely journaled on a shaft 28, which is permanently geared to the driving sha-ft 29 of' an electric motor 30 by means of a sprocket chain'3l, whereby said shaft rotates continuously. Y

Extending lengthwise of the body 1 isan endless belt conveyer 32, which inclines rearwardly and upwardly from 'a point adjacent to the inner end of the boom to a point overhanging the mine car 7. The conveyer belt isdriven in a direction which will cause the upper stretch thereof to travel rearwardly in the direction of the mine car 7 by means of a driving drum 33.Y This driving drum 33 is located at lthe forward end, of the conveyer and is fixed to a shaft 34, whose. ends are journaled in suitable bearings in the opposite sides of the wheeled body. The upper endof the conveyer belt is supported on an idler roller 35 whose end .periphery of the wheel 49 is portions are journaled in the bearing-blocks supports the winding drums 26 and 27, is

permanently geared to a shaft disposed between the axles 2 by means of a sprocket chain 41'. The shaft 40 is vpermanently geared to the driving drum 33 of the conveyer by means of a sprocketl chain 42. The shaft 40 is adapted to be geared to the rear axle to propel the machine forwards or backwards by means of a planetary transmission gearing. Said gearing comprises a driving sprocket 43 loosely journaled on the shaft 40 and connectedto a sprocket on the rear axle 'by means of a sprocketchain 44 and said rear aXle is permanently geared tothe front axle by means of a sprocket chain.45. The drive sprocket 43 is formed on one side with an internal gear 46 and has a flange on its opposite side provided with studs on which are 'journaled one or more pinions 47, which mesh with a pinion 48 fixed to the shaft 40,

Loosely journaled on' the shaft 40 on each side of the drive sprocket 43. are grooved wheels 49 and 50. The grooved wheel 49 'has one. or more pinions 51 journaled on studs which project from one side thereof, which pinions mesh` with the internal' gear 46 of the drive sprocket 43 and a pinion 52' ired to-theshaft 4 0. The grooved wheel is drive Sprocket 43 and is provided with an internal gear 53 which meshes with the pinions 47 on 'said drive sprocket. The grooved encircled by a contracting friction brake. band 57. This friction 'band is tightenedby means of an eccentric keyed. to a rock rod 55 which is provided with a foot lever 5 6. Manipulation of the foot lever 56 tightens thebrake band 57, which action holds the wheel 49 against rotation and thereby 4forces the.

located onthe opposite side of the drive sprocket 43 to rotate in a direction I which will drive the machine forward.

The grooved is encircled by band 54. This by means of an a contracting. friction brake friction bandis tightened is. provided with a foot lever 59 located adjacent to the foot lever 56. Manipulation of the lever 59 tightens the brake band 54'.-

machine rearward.

periphery of the wheel 49t eccentric keyed to a rock sleeve 58 gournaled on lthe rock rod 55 andv Adrums 26 and 27 The winding drums 26 and 27 are driven from the shaft 28 by means of planetary gearing in a manner-similar to the drive sprocket 43. The planetary gearing for the comprises two pinions, 28, one for each drum, which are fixed to the shaft 28 and mesh' with -one or more pinions 60a and 61 journaled on studs on groove wheels 60 and 61. These grooved wheels 60 and 61 are loosely journaled on the Ashaft 28 with their pinions meshing with the internal gear rings 26a and 27a formed in driving drums 26 and 27. The peripheral portions of the respective grooved wheels -60 and 61 are'encircled by contracting friction bands 62 and -63 similar to the brake bands 54 and 57. The friction band 62 is tightened to lock the wheel 60 to the shaft 28 by means of an eccentric keyed to a rock shaft 64 which is provided with an operating lever 65; and the fric-tion band 62 is tightened to lock the wheel 6l to said shaft 28 by means of an eccentric keyed'to a rock sleeve 66, which is journaled on said rock shaft 64 and is provided with an operatinglever 67 located adjacent to the operating lever 65.

iassuming that the machine, with the mine car coupled to the wheeled body thereof and with the lower end of the scoop in the position indicated in full lines in Fig. 2, has been self propelled along the mine track to bring the scoop close to the loose Amaterial to be loaded, the operation of the machine is as follows:

The motor 30 having been started, it will, of course, be evident, by reason of the respective sprocket chain connections 3l, 41' and 42 between the continuously operating` motor shaft 29, 'and the driving drum 33 of the conveyer 32, that the conveyer belt will be in continuous operation with its upper stretch moving toward the rear of the machine. The operator, standing on a platform 68 so 4as to be within easy reach of the hand levers -65 and 67 and the foot levers 56 and 59, then manipulates the foot` lever 56 to propel the wheeled body 1 forward, thereby forcing the scoop into the bottom of the pile of loose ore. ward movement of the machine, the hand. levers 65 and 67 are manipulated to cause the scoop to swing upwardly thus skimming its charge from the side of the pile. The scoop having been filled, the upward swinging movement thereof is continued until the back of the scoop rests uponthe uppervsurface of the `web portion of the boom. The operator continues to manipulate the hand levers 65 and 67, whereby the drums 26 and 27 continue to move in a winding direction and the continued pull on the scoop causes said boom to swing upwardly.

This upward swinging movement otthe boom causes the material to slide out of the During this forscoop onto the upper channel of the boom, 'which functions as a chute and delivers the material to the rearwardly moving upper stretch of the conveyer belt. The material is then carried to the delivery end of the Vconveyer where it is discharged into the mine car coupled to the -rear ofthe machine. This operation of filling the scoopand elevating the boom, to cause the contents of the scoop to slide down the boom onto the conveyer and be delivered to the mine car,

is continued until' said car has been filled,

whereupon the loaded car is replaced with.

an empty one.

The boom is swung to-and-fro, to enable.

a pile of ore to be removed from either side of the machine, by means of the chains 2i and 22, which are used for swinging the scoop over `the boom and for raising said boom.

These` chains are secured to the scoop on opposite sides thereof and are wound around separate winding drums. Thus, when it is desirlll to swing the boom to wards the side. ol' the machine on which the operator stands, the opera-tor manipulates the hand lever 65, whereby Lbe drum 26 i's rotated in a winding direction and the chain 21 attached to the operatng'sde of the scoop is wound on said drum, vthere-by causing the boom to swing both vertically and horizontally. When it is desired to swing the boom to the other side of the machine, the lever 67 is manipulated, whereby the)` pull is on the opposite side of the scoop thus causing the boom to be raised and swung,` away from the operator.

V'Vhen both levers 65 and 67 are simultaneously operated, the pull on the'opposite sides of the scoop is equal and the boom is caused to rise. without lateral movement.

The boom may be held in its elevated position a length of time sufficient to enable the contents of the scoopto reach the conveye-r by a slip pressure ofthe respective brake bands 5l and 57 on grooved wheels 49 and 50. This slip pressure may also be used to control the lowering moyement of the boom whereby the same may be lowered without shock.
